[0070] like Figure 6 As shown, the upper end of the shaft sleeve 98 is fixedly connected with the driven gear 62 , and the driven gear 62 is meshed with the driving gear 61 .

[0071] like Figure 1 , Figure 2 and Figure 6 As shown, the tank cover 3 is provided with a feed port 33 , an oil filling port 34 and a viewing window 32 .

[0072] The staff can observe the stirring status of the mixed material in the mixing tank 2 through the viewing window 32 .

[0073] like Figure 1 , Figure 2 and Figure 6 As shown, a feeding pipe 31 is provided at the feeding port 33 of the tank cover 3.

[0076] The oil filling pump 71 is installed on the upper surface of the tank cover 3, the oil inlet end of the oil filling pipe 72 is fixedly connected to the oil outlet end of the oil filling pump 71, and the oil outlet end of the oil filling pipe 72 is fixedly connected to the oil filling port 34 on the tank cover 3;

[0077] The connecting pipe 73 is fixedly connected to the oil inlet end of the oil injection pump 71 .

[0078] Connect one end of the oil extraction pipe to the connecting pipe 73, and then put the other end of the oil extraction pipe into the container containing oil, start the oil extraction pump, and the oil enters the mixing tank 2 through the oil extraction pipe and the oil filling pipe 72 under the action of the oil extraction pump.

[0079] According to the utility model, dry materials are first added into the mixing tank 2 from the feeding pipe 31, and the motor 1 5 is started. The motor 1 5 drives the stirring paddle to rotate. The stirring paddle first stirs the dry materials evenly, and then the oil is injected into the mixing tank 2 through the oil injection mechanism 7. At the same time, the motor 2 6 is started. When the motor 1 5 drives the stirring blade 83 and the scraper rod 84 in the stirring paddle to rotate, the stirring blade 83 stirs the mixture, and the scraper rod 84 drives the scraper bar 85 to rotate and scrapes off the grease and mixture sticking on the inner wall of the mixing tank 2. In this way, the grease and dry materials can be fully utilized, and the amount of grease and mixture adhering to the inner wall of the mixing tank 2 can be reduced, which is convenient for cleaning the mixing tank 2. The motor 2 6 drives the driving gear 61 to rotate. The driving gear 61 drives the driven gear 62 to rotate, and the driven gear 62 drives the connecting block 96 to rotate through the shaft sleeve 98. The connecting block 96 drives the bevel gear 2 93 and the rotating rod 94 to rotate around the bevel gear 1 92, and drives the housing 912 to rotate. At the same time, the bevel gear 2 93 rotates and drives the rotating rod 94 to rotate. The cutting blade 95 on the rotating rod 94 also rotates with the rotation of the rotating rod 94. Since the chassis 911 is fixed to the tank cover 3 through the connecting shaft 97, the chassis 911 and the bevel gear 1 92 will not rotate. In this way, the rotary cutting mechanism 9 can not only cut and granulate the mixture, but also assist the stirring mechanism to stir the mixture, so that the mixture is mixed more evenly and the obtained particles are more uniform. After the mixture is mixed, the push-pull device 44 is started, and the output end of the push-pull device 44 pulls open the bin door 42, and the mixture enters the discharge bin 41 through the discharge port 21 of the mixing tank 2, and falls into the container containing the mixture through the discharge pipe 43. After the discharge is completed, the output end of the push-pull device 44 pushes the bin door 42 toward the discharge port 21 of the mixing tank 2 to close the discharge port 21.
